IsDetachedPrimaryFile Method
Questa funzionalità verrà rimossa in una delle prossime versioni di Microsoft SQL Server. Evitare di utilizzare questa funzionalità in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni in cui è attualmente implementata.
The IsDetachedPrimaryFile method specifies whether a file is a detached primary database file.
Sintassi
object
.IsDetachedPrimaryFile(
MDFName
)
as Boolean
Parts
- object
Expression that evaluates to an object in the Applies To list.
- MDFName
String that contains the name of the primary Microsoft SQL Server database or log file.
Prototype (C/C++)
HRESULT IsDetachedPrimaryFile(
SQLDMO_LPCSTR MDFName,
LPBOOL pRetVal);
Osservazioni
Prior to calling IsDetachedPrimaryFile, an application should call the ListDetachedDBFiles property to retrieve a complete list of detached database files or ListDetachedLogFiles property to retrieve a complete list of detached log files. The application can then call IsDetachedPrimaryFile to determine which of the files is the primary file.
[!NOTA] If an application calls IsDetachedPrimaryFile on an instance of SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000 or later" are returned.
